"add 5 horsepower with your catback then possibly subtract 2 for your CAI. buy the more significart of your exhaust " I guess that makes it only 3...I was thinkin you said 10 for catback
I bet, because of all the timing being pulled because of bad MAF readings.
General rule - CBE = noise-maker (little, if any, performance gain)
If you want to get performance, the DP has 2 catalytic converters in it, and is restrictive on your engine. Get an aftermarket DP that is catless (removes both cats) or one with a high-flow cat and some EM, and you'll be liking your results.
Intakes/CBE do basically nothing for our car other than enhance the sound - as said, an intake can actually reduce the power of your vehicle (by making the car run lean).
